HT Cas

HT Cas is a binary system which emits X-rays. It has been observed with
the ASCAsatellite, from which astrophysicists have determined the
following about HT Cas:

It involves a smaller star that is a white dwarf and a larger star that
is nonetheless smaller than the Sun (the size of the larger star should
make sense, once you have made your calculations).

This system has an inclination of 83 degrees. A 90
degrees
inclination system would be one where the smaller star traverses the
central star exactly in the middle, providing some evidence that it
exhibits a Total Eclipse) in its light curve.
